1 Claim. 7 1

This invention relates to a station and street announcer and advertising device for use in railway cars and streetcars.

An object of the invention is to provide a device that will indicate the stations or streets as the latter are approached, such device being manually operated by the occupant of the vehicle, by means of a push button switch.

Another object of the invention i to provide a device which, by means of a time flasher, will automatically display advertising matter continuously during the operation of the vehicle to which it is attached.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is an elevational view of an embodiment of the invention partly broken away;

Figure 2 is an end view showing the mechanism in dotted lines;

Figure 3 is the same of the opposite end;

Figure 4 is an enlarged sectional view on the line-'4-4 of Figure 1;

Figure 5 is an enlarged sectional view On the line 5-5 of Figure 1;

Figure 6 is a sectional view on the line 6-6 of Figure 4; I

Figure '7 is an enlarged view on the line 1-1 of Figure 1 and Figure 8 is a diagrammatic view of the circuit wiring system for the device.

Referring more in detail to the drawings, the reference numeral I0 designates the housing of the device, which is substantially rectangular in cross-section, and is provided with a window opening I4, having inclined flanges I6 provided with recesses I8 to seat the pane of glass 20.

The housing I0 is provided with vertical partitions 22 and 24 respectively, adjacent the ends thereon, on which are mounted bearings 26 for mounting the transverse motor shaft 28, timing roller shaft 30, idler roller shaft 32, winding roller shafts 34 and 36 respectively, and pressure roller shaft 38. Shaft 28 is connected to the motor 40 mounted on the bracket 42 secured to the outer surface of the housing I0, and shafts 34 and 36 are provided on their outer ends outwardly of the housing In with hand cranks 44.

Mounted on the shaft 28 in opposed relation to each other are the beveled faced friction wheels 46 which engage the friction wheel 48 mounted on the clutch collar 50, which is keyed to shaft 52 for rotation therewith but is mounted for sliding coaction with shaft 52, which is journalled in bearings 54 secured to the housing and partition 24. The clutch collar is provided with a circular flange 56 which engages one end of the convoluted spring 58. The other end of the spring engages one of the bearings 54. A worm gear 60 is provided on the shaft 52 to engage the worm wheel 62. The measuring or spacer wheel 64 is mounted on the worm wheel 62 and the wheel is mounted on the timing roller 66 which in turn is mounted on the shaft 30.

The wheel 64 is provided with relatively spaced indentations 68 which engage a pin 10 on the timing arm 12 on which is provided the clutch arm I4, having the bifurcated end 16 which by means of opposed pins 18 is slidably connected to the clutch collar 50 for the operation thereof. A motor switch is secured to the clutch arm 14, and is adapted to engage a wire terminal 82 mounted on the partition 24.

The arm 12 is tensioned by a spring 8I mounted on the wing nut 86 positioned in the bracket 88 on the partition 24 and tightening of the nut through engagement of the spring with the arm tensions th arm for the operation thereof, and the opposite end of the arm 12 is positioned for engagement with ,a magnet 80 mounted on the housing I0 by means of brackets 92.

The curtain or web 94 i mounted on the spring winding roll 96 on shaft 34, passes over roll 66 on shaft 30 and idler roll 98 on shaft 32 to be wound on the spring winding roll I 00 on shaft 36. The pressure roller I02 mounted on shaft 38 which is journalled in bearings 26 in brackets slidably mounted in guide tracks I04 secured to the housing I0 engages the curtain 94 as it passes over the roller 66, and applies pressure thereto by means of the pressure springs I06, engaging the brackets I03 and the adjusting screw I08, threadably mounted in the internally threaded boss IIO formed on the housing I0, and guide tracks I04.

Mounted on the hand reversing lever H2 and adapted to engage the wheels 46 is roller II4, which will by manipulation of the lever 2 reverse the direction of travel of the curtain, and the lever is pivotally mounted in the apertured ears H6 on the partition 24 by means of the pin H8, and the wing nut I20 engaging the lever II2 retains it in operative position for the actuation of the wheels 46.

Mounted on the base of the housing In is the automatic two-way over-run and reversing switch I22 which is engaged by magnets I24 and 3 I26 mounted on partition 24 by means of brackets I28 to alternately contact the terminals I30 and I32 by means of the opposed contact arms I34 and I36, and the switch I22 is controlled by the over-run or reversing switches I38 which engage the curtain 94 for th operation thereof.

A reflector I40 and light I42 are provided, to illuminate the curtain 94 as it passes the window opening I4.

During operation of the device, a push button I44 is connected across one end of the conductors I46 and I41, the conductor I46 being connected to the magnet 90 while the conductor I41 is connected at I29 to the conductor I83 which connects the source of current I48 to the common terminal I25 of the magnets I24 and I26. The source of current I48 is also connected at terminal I3I to the conductor I33 which connects the magnet 90 to terminal I32 of the switch I32, thus the magnet 90 is connected through the source of current I48 and the current source I48 is connected to switch 80 by conductor I52 through the terminal I61, and terminal 82 is connected to the terminal I32" of the switch I32 by conductor I56 and terminal I3I i connected to one side of the switches I38 by conductor I58, the other side being connected to magnets I24 and I26 by conductors I60 and I6I, respectively. Terminal I54 of switch I22 is connected to one end of the field coil I59 of the motor I40 by conductor I65 and terminal I68 of the switch I22 is connected to the opposite end of the field coil I59 of the motor I40 by conductor I18. Terminal I30 of switch I30 is connected to motor terminal I69 of the motor I40 by conductor I12, while the terminal I30" of the switch I30 is connected to the motor terminal I12 of the motor I40 by the conductor I14.

This when the push button I44 is depressed, the circuit is completed, magnet 90 is energized, causing arm 12 to move out of engagement with the timing wheel 64 and engaging the wheel 48 with one of the wheels 46 and starting the motor, causing the worm 60 to rotate wheel 62 and roller 66, carrying the curtain with it until th arm 12 drops into the next indentation 68, and deenergizing the motor until the push button I44 is again depressed. The motor is of any size D. C. and is of the reversible type for the operation of the device.

Should it become desirable to reverse the curtain at any time lever H2 is operated to engage th oppositely positioned wheel 46, thereby reversing the travel of the curtain 94.

The curtain can contain station or street designations, and every time it moves, different stations or advertisements may be viewed through the window I4. The curtain passes between the contacts of the switch I38 so that current fails to pass therethrough, but apertures are provided adjacent the ends of the curtain, so that the contacts can engage and energize the magnets 4 I24 and I28 to reverse the travel of the curtain. The end of the curtain approaching the switch I38 determines which magnet is energized; thus the curtain is automatically reversed for the viewing thereof.

The housings can be connected in series so that a plurality of them may be used at various places in the vehicles and the push button switch can be replaced by a time flasher for the automatic operation of the device as an advertising medium.

Thus there has been provided a device which can be conveniently placed in a vehicle to display advertising or station or street designations. It is believed that from the foregoing description, when taken in conjunction with the illustration of the device, that one skilled in the art will understannd the operation and construction of the device and it is to be understood that changes in the details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A device of the character described. comprising a housing, a movable web in said housing, bearing thereon station or street designation or advertising, a plurality of rollers over which said web presses, said rollers arranged so that a portion of the web may be viewed through a window in said housing, a pressure roller engaging said web to force said web against one of said rollers, a motor shaft, a bevelled faced friction wheel on said shaft, a second shaft mounted at right angles to said motor shaft, a driven friction wheel on said second shaft adapted for coaction with said driving friction wheel, a clutch collar mounted at one end on said driven friction wheel, a circular flange on the opposite end of said clutch collar, a worm on said second shalt. a worm wheel on one of said rollers adapted to engage with said worm, a measuring means carried by said worm wheel, operating means engagin said measuring means and said clutch, means for operating said measuring means to cause said driven friction wheel to be selectively engaged by said driving friction wheel whereby said web is advanced a certain distance by said measuring means in relation to the operation of the means for operating said measuring means.
